Application tiled March 11, 1913. Serial Ho. 753,4?5.

To all whom it may concern:

lie it known that l, Josnrn Wnrrn, a citi- Zcn oi' the United States,residing in Piscataay township, (post-oiiice address, Bound Brook, NewJersey,) State of New Jersey, have invented certain new and usefullinprovements in Sheet-Delivery Mechanism; and I do declare thefollowing to be a full, true, and exact description of the saidinvention, such as will enable others skilled the art to which itappertains to make use of the same.

This invention relates to that form of sheet delivery mechanism in whichthe sheets are laid one by one on the delivery pile, and provides asimple and ofiicient means by which such sheets may be received in rapidsuccession from a printing machine or the like, and laid evenly andregularly on the lie.

The mechanism whica I havedevised is particularly useful in machinesfrom which the sheets are being delivered not only at a high rate ofspeed but with a very short distance between the successive sheets.\Vhen the usual torn s of delivery mechanisms are applied to such amachine, they will not work ell'iciently, particularly if they embody areciprocating carriage, since the time between the successivepresentation of the sheets to such carriage is not suilicient to permitthe carria to deliver the sheetand get back to the Sul ting point beforethe next sheet arrives.

My present invention is to provide a de livery mechanism, andparticularly one using a reciprocating carriage, which is so con--structed that it will deliver sheets presented to it in very rapidsuccession.

With this and other objects in view. my invention consists of certainnovel features oi constriustion and arrangement of parts as will be morefully described and pointed out in the appended claims.

Fig. (i is an enlarged partial side elevation ofsome of'the mechanism shown in Fig. l.

The corresponding parts are referred to both in the drawings and thefollowing de scription by similar reference characters,

in the drawings, 16 represents the impression cylinder of the printingpress w have chosen for purposes of illustration, and 11 a deliverycylinder therefor, the delivery cylinder illustrated being composed 01"a number of separate rings 12. In the particular form which I haveillustrated, this delivery cylinder is pro ided with two sets of sheetgrippers 13-- *zused to operate to take a sheet from the impressioncylinder 10 and to deliver it to the dei rv mechanism by cams 1l-15 inthe usi u manner. T he cylinder 11 is geared the cylinder 10 to bedriven uniformly the ewith.

16 is a sheet delivery tray on which. the sheets are to be piled andwhich'is supported i1);Y a manner to be more-fully described here a D1Between the deliv ry tray 16 and the cylinder ii is mounted areciprocable carriage- 1T composed of a shaft l8 having mounted thereona :pport 19 which, in my preferred form, is composed of a plurality ofseparate members attached to the shaft 18. The shaft 18 is mounted inblocks ':2 U21. which are slidably mounted on a pair of parallel bars orsupports 22L2l, seemed in any suitable manner to the sideiframes oi thepress. To the blocks Elle--21 are connected connectingrods which inturn, are connected to levers 2i"-27 attached on either side oi thedelivery pile to a shaft extending across the side frames of the press.To the shaft 28 is attached a lever 29 connected by a rod 30 to a crankarm 31 mounted on a 32 meshing with a gear 33 on the shai't 'ofl thecylinder 11. The gene 33 is twice as large as the gear 32, and as willbe seen by an inspection of Fi a 1, the carriage 17 moves back and forthtwice for each rotation of the cylinder 11, and in timed rela. tiontherewith. i

To the shaft- 13 is attached one or more arms 34c against which isplaced an arm 35,

. loosely mounted on the shaft 18 and con reacted to the orni 534i hy'z.spring 36. The fil'll'l' carries a roller 37. An inspection of Fig. Gwill show that the roller. 57 is capable of an up and down motion aroundthe shaft 18, out is normally held in its.

uppermostposition by the springBG.

Rotatahly mounted in the side frames of the machine is u shaft 38carrying one or more arms 39 attached thereto, such arms carryingrollers and bein shaped so as to provide a stop member 4-1 thereon. Therollers 4:0 are held normally in the position shown in Fig. (l by thespring 92 turning the shaft 38 but, through the connecting rod and camlever 4% moved by the cam attached to the shaft of the cylinder ll, the

rollers 40 may be moved to the position shown in F 19;. 1'.

liotatahly mounted in the side frames of the machine 15 a shaft 42-6 towhich is at-' taohed one or more arms 47, these urrrs being; tt-I'I1!ll'8(l to plies between the rings 12 the cylinder ll'and to he, heldnormally within the, periphery of, these rings hy the spring 48. Theamnell are moved to position shown in Fi .1 by the cam. 4.9 actingthrough the cam lever and the connecting rod 51.

Referring: now particularly to 3, 4, and 5, it wil be seen that theparts heretofore described are arranged in such a mare ner that whilethe carriage 17 is still mov ing backward or to the right of Fig. 3, thegrippers 13 of the cylii'ider 11. open to permit the hood of the sheetto pass to the riage 17. At this time the. roller 37 has been. pressedupward henna tthe cylinder 11, and thus acts in coiiperetioii W "lderll. to feed the sheet from the cy nder to the car-- ringe The yieldingmouutingro'f the roller 3? eneoles it to remain in contact with thesurface of the cylinder 11 as the car iage 17 moves to the rightand' tothe left of Fig. 3. i shown in Fig. 21s the sheet begins to pass. to thecarriage 17, the arms 47 are with-.

in the periphery of the cylinder, and therefore do not interfere withthe sheet. The

rollers 46 and steps 1-1 are held in their uppernioet positi-rui by thespring 42, and in this posit-ion. arrangedto engage the head of thesheet as it moves, along; the car- 1'5. The stops 4:1 are positioned sothat the" extend below the surface of the supp-or 1.9, and the rollers40 are pose tinned so that they run on. t p of these supports. Thus the'lri'nit edge of the. sheet under the rollers; i!)- and hits agnnnet thestops 41 at a time when the carriage l7 ie moving: in the but at a lessspeed, the rollers 40 serving to hold the shee to the carriage l7 illhlll!) )10- vent its rebounding from the stops H.

The carriage fl'i is constructed so that 1e rn'ijzch shorter than thelength sheet which me as? the position shown in Fig. 5 during which timethe front edge of the sheet is tucked under the rollers 40 andagainstthe stops 41, so that the further movement of this edge isprevented. he continued i'noveinent of the carriage moves it out fromunder the sheet when it arrives inthe position. shown in F i";

5, at which time the cams l5 and 49 operateto move the rollers 40 andthe arms 47 downward, thus forcing the sheet to drop to the pile. A

By reason of the short distance which the carriage to travelli:'.-=".kwm'd,- or to therightof Fig. 5, in order to receive the headof the next sheet, the sheets may be deliv ered in rapid succession. Inthe form illustrated, for instance, the distance between the tail. andthe head of successive. sheets is somewhat less than half the totallength of the sheets.

As will he understood from an inspection of Fig. 1, immediately afterthe rollers 40 and the arms &7 have moved downward to oe 'ioeit thesheet, they arerestored to their original or upward position as shown inFig. It will also he understood. that the backward motion of thecarriage 17 to the right of T5,. 5 will bring the roller 37 again incontact wi l the next sheet; on the cylinder 3/? hold iheroae'ainst. andto compel its delivery to the carriage 17.

lit will he understood that the arms 47 are not always required, thoughI prefer to use them. It will also he understood that the roller 87 maybe mounted in any appropri ate manner other than the 0ne-which I haveillustrated, although. I prefer the latter since the mot-ion of thecarriage provides a ready means by which these rollers may be moved fromheneath the sheet to permit it to drop.

One of the principal advantages of my etter was: fed to it.

very short carriage and one having a very short stroke, and also e hles'the eiently rapid removal of the carriage from hlo the earriage toceueeth the eh et "o n return to the end I t,

This enables me to use first. For some purposes a carriage other than areciprocating one may he used.

While for the tray 16 may be substituted any of the well-known forms ofdelivery board, I prefer to use the tray arrangement illustrated in Fig.1, although it forms no partof my present invention, being separatelydescribed and claimed in my application for Letters Patent Serial No.726,592, filed October 19, 1912.

Referring now to Fig. 1, 60 represents one of a pair of narrow supportson either side of the mechanism on which is slidaloly mounted the tray16 by means of grooved projections 61 thereon, the rear end of the traybeing supported by a projecting ledge 62 attached to the support 60. Thetray lb is provided at either end with an end member 63, 6 1 Thetray 16may be inserted heneath the cylinder 11 by placing the grooved member 61on the support 60 and pushing it inward until further progress isprevented by a removable stop pivotally mounted at 66 on the side frameof the machine, it being understood that the stop 65 will normallyengage with the inner edge of the end memher 6%. l Vhen it is desired toinsert a new tray after the tray 16 is filled, an empty tray, a portionof which is shown ii dotted outlines in Fig. l, is placed on the s Aorts with grooved members 6.1 en aging therewith. When this empty trayis moved sutliciently far inward so that its end menu her abuts the endmemberfit of the full tray, the stop will have been raised out ofcontact with the end member 6-: by the engagement of the supporting armof the stop 65 with a portion of the incoming tray. Further motion ofthe incoming tray will. cause the full tray 16 to move along thesupports 60 until its grooved members 61 move l ieyond the end of thesupport (30. and its rear portion pa beyond the ledge (52. The filledtray 16 will then fall downward and be caught on a set of spring, seatedplungers 67. The incoming tray may then be pushed into the place of thefull tray, the stop 65 moving downward to engage with the end member 64-of the empty tray to locate it in place. The filled tray 16 may then hemoved backward at any convenient time and removed from the press. An endstop 68 is provided to prevent the tray being moved too far to the leftin Fig. 1.
